Abstract
A measurement method for the absorbed energy to the adhesive joints fractured by subjecting impact loads was studied. One-dimensional elastic wave theory was used for the calculation of the absorbed energy. The experimental equipment which can apply the theory was developed. The performance of the experimental equipment was investigated. Specimens were manufactured using the adhesion tape. The absorbed energy when this adhesion tape is fracturing is small. As a result of the experiments, It found that the measurement of energy is possible even if the value of fracture energy was very small. As the above result, it was thought that the precision of this measurement method is high sufficiently.
